Introduction to Nuclear Power Cable Trays

Home / Introduction to Nuclear Power Cable Trays

Cable tray systems are very popular in nuclear power plants (NPP), which are generally multi-span steel structures suspended from the ceiling, or mounted on ground or floor levels of the building structure. This appendix provides the design criteria for seismic Category I cable trays and their supports. The Pacific Earthquake Engineering Research (PEER) Centre has been developing a performance-based earthquake engineering (PBEE) methodology, which is based on explicit determination of performance, e. Search within the title, abstract, claims, or full patent document: You can restrict your search to a specific field using field names. For qualification of the effect of the protection measures, small-scale tests investigating a single cable specimen as well as large-scale cable tray test setups were developed and car-ried out in the. Nova, a product and service brand of Curtiss-Wright Nuclear, supplies safety-related cable tray systems that are manufactured to current NEMA VE1 specifications to the nuclear industry and other power generation industries.
